How do you feel about sharing spaces with "transmen"?

[BTT]

Should women be happy with sharing spaces (public conveniences, changing rooms etc.) with "transmen" (that is biological females) who have made themselves look like biological males and have beards and muscles etc. Wouldn't that be necessary if we segregate people by sex? Does it happen now? I am a conventional man who is thinking about how we should segregate people regarding those spaces and the difficulties it presents. I can understand (to the extent a man can) that women have good reason to be wary of men or anyone perceived to be one.

Many men don't want to share toilets with women either.
At a recent sporting event there were gender neutral toilets, not the ones with a row of stalls to be accessed from the outside but an actual room behind a door if that makes sense?
As I went to go in DS16 and his friends were behind me but stopped dead when they saw me go it and waited outside "to make sure I was Ok" until I came out

Not bothered. As long as the loo I'm in has a lockable door, I don't care who else is in there.
